Fire rated sealant for homes and businesses in Lower North Dean

We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you’re dealing with holes left by a change of layout and joints picked up in a fire-stopping survey, we can help.

If you have holiday lets, a converted barn used for business or a community building near Lower North Dean, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Whatever the size of the job, it’s backed by our one-year guarantee in Lower North Dean and across Buckinghamshire.

Fire rated sealant in Lower North Dean: local notes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

Letting a property close to Saunderton station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Speen Church (Baptist), older buildings that have had new heating or wiring often have service gaps worth checking.

The process

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the amount of work. For a village or hamlet like Lower North Dean, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit

Do you need fire rated sealant in Lower North Dean?

In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.

Common reasons people contact us are:

  • Standard silicone or caulk in a fire-stopping gap
  • Holes left by a change of layout
  • Joints picked up in a fire-stopping survey
  • Door frames with gaps between frame and wall

If you look after a building such as Hughenden Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Before you book anyone

  • What insurance they hold
  • What happens if they find a problem under the old sealant
  • What the cure time is
  • How the colour is chosen

What we can’t put right

It helps to know what we can’t do too:

  • Certifying a building or signing off its fire safety
  • Assessing a building’s fire safety
  • Problems with the door itself rather than the gap around the frame

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Surfaces we seal

  • Pipe & cable gaps
  • Plasterboard & masonry
  • Service penetrations
  • Door frames
  • Flats & HMOs
  • Linear gaps

For landlords and businesses

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.

Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Don’t paint over fire sealant until it has cured
  • Get damaged fire seals looked at promptly
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Ask every contractor to reseal any fire stopping they disturb

Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.

FAQs for Lower North Dean

Do you cover smaller places like Lower North Dean?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you cover Lower North Dean for fire rated sealant?

Yes. We work across London and the South East, and Lower North Dean is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.

How long does fire rated sealant take?

A typical job takes a few hours for a handful of gaps, and longer for a whole building, including the preparation. We’ll confirm how long when we quote.

Do you remove the old sealant?

Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

What does fire rated sealant cost?

Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.

Where do you work from?

We work from Crawley. Our applicators cover Lower North Dean.

Why it’s worth doing now in Lower North Dean

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own and needn’t wait for anything else. Where a wall is exposed, as many are in small places like Lower North Dean, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
